Abstract
An optical communication unit includes a light emitting element for emitting a transmission signal light; a condenser lens for coupling the transmission signal light from the light emitting element to an optical transmission path; and a light receiving element for receiving a receiving signal light from the optical transmission path. A light emitting surface in the light emitting element is formed by a plane tilted to a perpendicular plane in a substrate surface of a chip in the light emitting element.
